Study Notes
Biceps Tendon Reflex Test
- Tests the musculocutaneous nerve and C5–6 spinal cord segments.
- Abnormal responses (excessive, diminished, prolonged) can signal issues with the central or peripheral nervous system, or metabolic disorders.
- Performed with the patient's arm gently flexed at the elbow.
- The biceps tendon is tapped with a reflex hammer (or, for demonstration, the examiner's thumb).
- This technique can be made more effective by first locating the tendon with the examiner's thumb.
